After your next 'svn update' you need to get the latest chandlerdb version by
running in 'chandler':
make chandlerdb - OR -
make install
The changes include the addition of a new isitem(foo) API, a faster,
not-so-foolable version of isinstance(foo, Item).
Support for the new -V / --verify-assignments command line option is also in
there. To turn on literal attribute assignment verification (bi-refs are and
were always checked), use -V or --verify-assignments.
